how to make my printer print on both sides of the paper

Then arrange the stack of paper for printing on the other side. When printing finishes, if mpage reported an odd number of pages, remove the last one from the stack, since there will be no even-numbered sheet to match it. (Only half this many will really be printed). If you use 3-hole punched paper, put it in the printer such that the holes will appear at the top of the page - on the right as you pull out the printer tray, in our Laser writer II NTX. You can do double-sided printing, in two passes, as follows. Thus -j1-10 selects the first 10 sheets, while -j 1%2 prints just the odd- numbered sheets and -j 2%2 prints just the even ones. Here last defaults to the end of data, interval to 1. Print just the selected sheets, specified by number, starting at 1.

If you print from the command line, you can also do this with mpage. Many graphical applications like let you do that. If double sided printing is not supported by your printer, you can also achieve this by printing odd/even (or right/left) pages separately.
